Geophysical Methods for Vein Imaging (2 replies and 2 comments)

Hello Everyone, we have recently acquired a claim with an old mine on it. We took some grab samples from inside the mine. We took samples from both the vein, and altered wall rock. We have done roughly 5 sets of testing with an average grade of ~15g/t AU. We have also had mineralogical analyses done and the mineralogy is consistent with a "orogenic lode gold" deposit. The vein and surrounding sulphidization has followed what appears to be a second order fault. In the vein the main sulphide is Arsenopyrite (~35%). The surrounding wall rock is altered to :illite and orthoclase (~70%)  with Pyrite and Pyrrohtite veins (~2%).  Their is minor chloritization in adjacent wallrock. What would be the best geophysical method to image the vein or stock work, aerial or otherwise.

Thanks for your help in advance!

Hi there, the best and sufficient geophysical method for sulfide veins is IP/RS          (Induced Polarization/ Resistivity Sounding). with this method, you can detect the vein up to 200 m in depth and it can give an acceptable 3D view for additional exploration or in detail exploration stage. preparing drilling design plan including the number of drilling, their pattern, depth, and dip, based on geophysical studies will prevent high drilling costs and also any blind drillings.

Of course, the exact identification of nearby rocks units and the preparation of a large-scale geological map prior to the geophysical operations is obligatory.  

Please do not hesitate to contact me if you require further information.

Thanks for your help! That's what we were thinking just from research, but we not sure if it was the best in practice. We have personally already mapped the area and are fairly confident with the geologic map. Is this a common method if we were to reach out to local companies, or is it something that we should go with a specific company?

I appreciate all of your help.

Hi Mattiel, 

Will IP / RS possibly also work on Group II kimberlite fissures?  

The fissures are sub-vertical and intruded into sandstones and shales with wall rock contact alteration of calcite and pyrite (+/- 2%). 

Thank you
